Hmm, I don't think that you can use the 3-click comfort update, as this is a completely new version of Limesurvey with a different code base. I think you will have to download it and install it manually.

I actually would install it in parallel to the old version, so you can still run your old surveys without a problem and you start new with 2.0.

I will have a look in my version. I am not sure if there is really an option to upgrade. It would make sense, but I personally would prefer to install the new version in parallel, as there have been many code changes.

I just updated my 1.92installation to Version 1.92+ Build 120919 and I do not receive any option to update to 2.00+.

There is no official release announcement because we want to see if any major issues might show up.
When having a so called "silent release" by just setting it at latest version, only some of our users will download it and if we find any major issues, we can fix them before thousand of users have downloaded a new version (which can never be fully tested).

The ComfortUpdate also takes some time to be adjusted which is the reason why it is not directly available after a new version was released, but some days/weeks later.
